When people think about weather they think about short-term changes in the atmosphere.
B. The length of time over which the conditions are measured
In the endosymbiont theory, an engulfed prokaryote that could perform respiration evolved over the generations into mitochondria providing the cell with an efficient means of producing ATP from organic compounds.
Similarly, an engulfed prokaryote that could perform photosynthesis evolved over the generations into chloroplast providing the cell with sunlight-generated sugar.
Explanation:
Endosymbiosis is the mutual relationship between two organisms. The theory explains that eukaryotes have evolved from prokaryotic cell or organism.
The host eukaryotic cell engulfed bacteria or prokaryote as bacteria was once an independent entity which could perform cellular respiration and photosynthesis. Possibility of one more cell which engulfed other cells is there.
Mitochondria have its own DNA and is the centre of ATP production which suggests that mitochondria has evolved over the time by photosynthetic bacteria. Sequence analysis also suggest that mitochondria had evolved from eubacteria.
The bacteria integrated into plant cell able to perform photosynthesis has evolved in to chloroplast int the plant cells.
Answer:
Commonly, we think of a theory as a kind of guess or "hunch." In science, a theory is much more. A scientific theory is an explanation supported by a large amount of evidence.

<h2>Karyotype Process</h2>
Explanation:
- <em>A organism has 46 chromosomes in its karyotype</em>. Its gametes must have <em>23 chromosomes</em>
- After <em>telophase I of meiosis,</em> the chromosomal consist of every daughter cell is <em>haploid</em>, and the chromosomes are each made out of <em>two chromatids</em>
- <em>Human somatic cells have 46 chromosomes, </em>including <em>22 homologous </em>sets and one sets of nonhomologous sex chromosomes. It is a <em>2n, or diploid,</em> condition.
- Human gametes have <em>23 chromosomes</em>, one every one of 23 interesting chromosomes. <em>This is the n, or haploid, condition</em>
